This Wifi Robot that Jonathan Bennett created is very well put together, best of all it was built on a budget. The five dollar base car that the hardware is mounted to is proof of that.

"A remote control car that can be driven over the internet or with a laptop wirelessly from up to 500m away. It has a live-feed network camera so that it can be driven without line of sight and a horn so that you can honk at people. Adding a network camera, router, heavier batteries, extra circuits, and a whole bunch of wires adds a lot of extra weight that the car wasn’t designed for. Because of all of the additions, you’ll need to find a pretty large RC car. Thrift stores often sell RC vehicles (without remotes!) for $3-5. I have bought a number of cars this way for taking apart. Vehicles in the 1:10 size ratio or bigger are appropriate; you probably don’t want to go any smaller. I bought this car for $5 at Value Village."

The steering system is simply a dc motor with a wiper position sensor. A PIC16F628A microcontroller is interfaced to the car’s original drive circuitry. The router has been modified to have a serial port. The serial port is connected the microcontroller.

Excellent model. Exactly what I was thinking to make. I m also working on a similar kind of thing. However, there are many significant changes in terms of features.
I just want additional technical details for this. Anyone Please………
